Chronic Wounds in Children: Prevalence, Aetiological Types and Predilection Sites in a Rural Setting in an Emerging Economy

The aim of this study was to determine the prevalence, aetiological types and predilection sites of chronic wounds in children. This study was a cross sectional study conducted on children aged 0-15 years. Through cluster sampling technique, children with wounds were recruited and evaluated. Demographic and clinical data were collected and analyzed. Descriptive statistics were used to summarize variables and Chi-squared test was used to achieve comparison between age groups and sexes. Statistical significance was defined as p<0.05. The results show that one thousand and ten children were screened for wounds out of which 107 children with 115 wounds were found. 16.5% of these wounds were chronic with a prevalence rate of 2.0%. Chronic wound prevalences in the school aged (47.4%) and adolescent (52.6%) children were 0.9% and 1.0% respectively (x2 = 0.821; p = 0.359 Yates’ corrected, Fisher’s exact test 2-sided) and statistically insignificant. 57.9% were caused by trauma and majority (89.5%) occurred in the lower limbs (x2=0.000; p=1.000 Yates’ corrected, Fisher’s exact test 2-sided) without any statistical significance. Prevalence of chronic wounds in the children population was very low. The commonest aetiological type was inadequately treated traumatic wounds which progressively healed on institution of appropriate wound treatment

Preservatve Potentials of Datura metel Seed Oil on Triplochiton scleroxylon Wood (Schumann)against Fungal Attack

This experiment was carried out to evaluate the potential of extracted Datura metel seed oil as a  bio wood preservative against fungi attack as reports have shown bio-preservatives to be toxic free and environmentally friendly. The oil was extracted from the seed by Soxhlet apparatus using N-Hexane and ethanol solvents and using volume-to-volume method of dilution kerosene (at 50%) was added to increase its quantity thereafter. The phytochemical screening of the seed of Datura metel revealed the presence of tannins, alkaloids, flavonoids, saponins and phenols. Wood samples of Triplochiton sceleroxylon  were cut to 20 × 20 × 60mm and the dimensioned wood samples were soaked for 72 hours in the seed oil extract hence preservative absorption rate and percentage weight loss of wood  was determined on exposure to a purely cultured Sclerotium rolfsil (brown rot fungi) and Pleurotus ostreatus(white rot fungi). Data obtained were subjected to analysis of variance at α0.05 and the results showed the highest value of mean weight loss of 18.29% while the samples exposed to brown rot fungi has a mean value of 14.12% and white rot a lowest mean value of 12.72%. The highest absorption was observed to be 92.73 kg/m at 100 % concentration level of D,metel extract.  Based on the results obtained, the seed-oil extracts of Datura metel have the potential of being an effective wood preservative

Microbial Spectrum and Antibiogram of Non-surgical Wounds in Children in a Rural Setting in Nigeria

The aim of this study was to determine the microbial spectrum and susceptibility pattern of non-surgical wound infections in children in a rural setting in our environment. This study was a cross sectional study of children aged 0 to 15 years in Bakassi, Nigeria. The children were screened for non-surgical wounds using an interviewer administered semi-structured questionnaire. Identified wounds were evaluated clinically for signs of infection and specimens were collected and cultured using standard microbiologic techniques. Susceptibility test was performed on all the isolated Micro-organisms. Data were collected and analysed using SPSS version 20 for windows. Sixty four wound infections out of a total of 115 wounds giving an infection rate of 55.7% were encountered. Of 64 wound cultures, 46.9% (30/64,) yielded mono-microbial growth, while poly-microbial growth of two and three microorganisms were obtained in 46.9% (30/64) and 1.6% (1/64) specimens respectively.A total of 92 organisms were isolated belonging to seven different species. Staphylococcus aureus (n= 57/92, 62.0%) and Streptococcus pyogenes (n = 30/92, 32.6%) were the predominant pathogens isolated. High rate of community acquired Methicillin Resistant Staphylococcus aureus (MRSA) (38/57, 66.7%) was observed. The microbial spectrum of non-surgical wounds of children in rural communities is wide. The high rate of antimicrobial resistance particularly MRSA and high predominance of S. pyogenes are potential sources of dire consequence in management and long term morbidity
